While there’s an option on my account to opt in to email updates, there doesn’t appear to be an option to opt out of physical ones. I’m interested because my not-quite-five-year-old got a mailshot which, frankly, isn’t much use to him as he’s not going to be booking his own tickets or making use of a discount!

I’ve emailed PD to ask about opting out of mailshots, or for them to consider filtering out under 5s from the mailing list.

And the response from PD, paraphrased: They filter out under 4s, but include everyone else as they feel kids like getting proper letters. They are happy to opt-out people from mail shots on request, just email admin@profounddecisions.co.uk.
